EGG FREEZE
EGG FREEZE
The woman's eggs can be frozen and stored for later use. Today, due to the long education period of women and their career planning, the gestational age has shifted to advanced ages. This may prevent women's reproductive ability to decrease and many women with this condition from having children. The development of assisted reproductive techniques and freezing methods has been a savior for women in this situation.
Another situation where egg freezing is the solution is oncology patients. Cancer is no longer a fatal disease for most patients, it is a treatable disease that does not shorten the expected lifespan. These patients regain their health with the help of chemotherapy and radiotherapy, but depending on the treatments applied, their ovarian reserves are depleted and they lose their reproductive ability. Thanks to the eggs frozen before chemotherapy and radiotherapy, these mistakes can become mothers when they regain their health.
The higher the number of frozen eggs, the higher the woman's chance of having children in the future.
Egg freezing can be done with a board report as per the IVF regulations.
The patient whose egg is to be frozen is first treated with eggs. Generally, progesterone suppressed protocols are used in these patients because there will be no transfer.
Treatment is started with gonadotropin hormone following the ultrasound examination on the 2nd or 3rd day of menstrual bleeding. On the same day or the next day, oral progesterone hormone (duphaston or tarlusal) is started and the progesterone hormone is used until the egg is collected. The patient is called for control after 5 days and the development of the follicles (formations containing the egg) is evaluated by ultrasound and if necessary, the E2 hormone level is checked. The patient is called for control at certain intervals (every other day or every other day). Follicle development is followed by ultrasound examination and, if necessary, E2 hormone values. When the leading follicles reach a diameter of 17-18 mm, HCG hormone is produced and egg collection is performed 36 hours later. In protocols suppressed by progesterone hormone, GnRH analog can be used instead of HCG hormone.
In patients who will be treated for cancer, treatment can be started on any day of the cycle in order not to waste time in their treatment.
After the eggs are collected, they are stored in liquid nitrogen tanks at -180 degrees after being frozen by the vitrification method. When there is a desire for a child, the embryos formed after these frozen eggs are thawed and fertilized with the micro-injection method are either transferred to the mother-to-be prepared simultaneously, or frozen as embryos again and transferred to the prepared woman.
